I have 4 cubes running on 3 different power supplies, an Antec 1200, a Corsair CX750, and one on a Rocketfish 500W I had lying around. Right now, switching the clock to high makes no difference in the speed -- they all hover around 29.5GH/s, whether in high or low. When I set up the first one, it did overclock up into the mid 30's... then I got distracted setting up the rest, and never really noticed when everything changed. Any ideas at all? I'm not sure where to start on this one.
Potentially might be limited by proxy or network topology limiting hash rate.
Ok! That's kind of the direction I was going, too. I did just add a switch in order to increase ports. But I'm lousy with networking, any further thoughts? Is having a switch bad? But I needed more ports.. ugh.
